disk brake conversion help
I am having a problem with my new brake conversion. I bought the kit back from "inline tube" in 2007 to convert my 1966 GTO drums to front disk brakes. I finally have had the opportunity to install them on my car. After installation. I was taking the car for a drive today and the front disks will not lock up. Slowed the car down, but would not lock up. I could lock up the rear brakes if I pressed hard enough on the brake pedal. I have a medium hard brake pedal. I know the brakes are put on correctly. We bled the brakes several times after a few drives with no help. My friend who builds hot rods and helped me install the brakes thought that it might be the brake booster. Could the brake booster have gone bad after sitting so long? Is there an adjuster on the proportioning valve? Do you have any Ideas why the front disks will not engage properly? Thanks FB66

Proportioning valve check
Hi,
I could be wrong but did you change the proportioning valve? I ask because by changing to a front disc/rear drum kit. It calls for a different proportioning valve. It will distribute the fluid properly and pressure properly. I hope this helps. Sounds like this could be your issue. |

Why not call Inline Tube?

Did you seat the pads or immediately making hard stops? Are your rotors blue now?

This thread is one of numerous threads created by OP on this topic. Last I read (in one of the other threads) was that he suspected he had a bad booster.
